From what you've described it sounds like you could be riding too close to the boat or too fast. You ideally want a rope length that makes you hit the wake a foot or 2 in front of where it curls and washes out. That is where the wake is steepest and lippiest.

My wake gets soft when the boat is too slow with too much weight in the rear. If I get some weight up front 50/50 and jump up around 22 mph, gets firm and clean. This is in a 21v, not sure if it will work for you or not.

Ray, That is a little slow and there is no reason that boat can't make a meaty wake.

Try two sacs 500-700 on each side of the motor-cover shifted all the way to the back seat and one more sack through the walkway up the bow. Also, consider bumping your speed up to 22-23 and letting you line out a bit too. A pro-sport is an old pro-star 205 hull I believe and I have a lot of experience with that boat.

You are going to want to speed up to 21 22 mph. An add a little to the nose. 18-19 is a little slow and probably not allowing the hull to get up on plane fully. I know when I pull my daughter at 17-19 it really doesn't shape up til 20 and lose the wash n curl.
